README file for replication code: Michael Clemens, Claudio Montenegro, and Lant Pritchett, "The Place Premium: Bounding the Price Equivalent of Migration Barriers", June 18, 2018.

Replication files:

1. "place premium online code.do": Stata 15.1 code that produces all table and figures in the main manuscript and online appendix.

2. "full_sample_ready_small.dta": Stata 15.1 data file containing microdata proprietary to the World Bank that cannot be publicly posted.

*Note* that the code requires two user-written packages, -bsweights- and -svmat2-, which are available by entering "net search bsweights" and "net search svmat2" on the Stata command line.

The code produces a series of .tex, .dta, .pdf., and .smcl files in the working directory. The correspondence between these files and the tables and figures in the paper and appendix are indicated within the .do file.

The provenance of all microdata for the United States is the US Census Bureau, as explained in the appendix. The provenance for all other countries' microdata is the World Bank's proprietary I2D2 database, as detailed in the appendix. Questions regarding the I2D2 database may be directed to Claudio Montenegro (cmontenegro@worldbank.org).
